1-1/2 inch Copper Coupling with Stop Copper

1-1/2” Copper Coupling – Lead-Free, Code-Compliant Pipe Connector

The 1-1/2” Copper Coupling is designed for secure inline connections in copper piping systems where continuity and leak resistance are critical. Suitable for use in potable water distribution, hydronic heating, and general plumbing assemblies, this coupling ensures a consistent internal diameter to maintain flow characteristics and system integrity.

Formed from lead-free wrought copper material, this fitting meets current U.S. code requirements for use in potable water applications. Its smooth bore and precise dimensions support clean joint construction and reduced turbulence across connected sections.

Performance Highlights

• ✅ Wrought Copper Body Fabricated to ASTM B75/B88 standards for mechanical strength and corrosion resistance.
• ✅ Uniform Socket Depth Allows for consistent solder flow and optimal engagement during sweat connections.
• ✅ NSF/ANSI 61 Certified Complies with lead-free legislation for drinking water systems across all jurisdictions.
• ✅ Thermal Compatibility Rated for soldering applications and capable of operating under hot and cold service conditions.
• ✅ Clean Interior Finish Supports improved hydraulic efficiency and reduced risk of particulate retention or buildup.

Specifications

• Size: 1-1/2 inch nominal
• Material: Lead-free copper alloy
• Connection Type: Sweat (solder)
• Applicable Standards: ASTM B88, ANSI/NSF 61, ANSI/ASME B16.22

Installation Notes

Ensure pipe ends are deburred, cleaned, and dry-fitted prior to flux application. Use lead-free solder and flux formulated for potable water systems. Heating should be applied evenly around the joint to promote uniform solder flow. Proper ventilation and safety compliance are advised during the soldering process, especially in confined areas.

Common Applications

This coupling is widely used in branch and mainline connections for hot and cold water systems, recirculation loops, and residential supply lines. Its compact profile makes it ideal for close-quarters installations where pipe alignment must remain precise.

Code Insight

Lead-free copper fittings are mandated by the Safe Drinking Water Act and applicable plumbing codes in all 50 states. This 1-1/2” coupling meets current NSF 61 requirements for health and safety in potable water systems.

Engineered for professional-grade installations, the 1-1/2” Copper Coupling supports compliant system layouts, clean joint integrity, and reliable long-term performance across a wide range of copper piping applications.
